我有字符串数据，其中包含一些英文字符和一些中文字符。我正在使用iTextSharp创建包含此数据的pdf文件。创建pdf文件后，当我打开它时，pdf只包含英文字符。它没有显示汉字。
你能告诉我如何在pdf文件中显示中文字符吗？请注意，我写给pdf的字符串数据包含动态语言字符，有时是英语，有时是中文，有时是日语等。

推荐答案

这在iText（夏普）文档中有说明。当你有一个包含不同语言的字形的字符串时，你需要使用<$ h $ => http://sourceforge.net/p/itextsharp/中的 FontSelector 。 code / HEAD / tree / trunk / book / iTextExamplesWeb / iTextExamplesWeb / iTextInAction2Ed / Chapter11 / FontSelectionExample.csrel =nofollow>这个例子。

This is explained in the iText(Sharp) documentation. When you have a String with glyphs from different languages, you need to use a FontSelector as shown in this example.

FontSelector selector = new FontSelector();
selector.AddFont(FontFactory.GetFont(FontFactory.TIMES_ROMAN, 12));
selector.AddFont(FontFactory.GetFont("MSung-Light", "UniCNS-UCS2-H", BaseFont.NOT_EMBEDDED));
Phrase ph = selector.Process(TEXT);
document.Add(new Paragraph(ph)); 

在这种情况下，我首先将Times Roman添加到字体选择器，然后是MSung-Light。现在 TEXT 中的所有英文字符都将出现在Times Roman中。您说缺少的字符将使用MSung-Light呈现。如果您更改了MSung-Light和Times Roman的顺序，完整的 TEXT 将在MSung-Light中呈现，因此请确保明智地选择字体。订单很重要，你没有定义字体的 TEXT 中的每个字符都将丢失。

In this case, I add Times Roman to the font selector first, following by MSung-Light. Now all the English characters in TEXT will be in Times Roman. The characters you say are missing will be rendered using MSung-Light. If you change the order of MSung-Light and Times Roman, the complete TEXT will be rendered in MSung-Light, so make sure you choose your fonts wisely. The order matters, and every character in your TEXT for which you didn't define a font will be missing.
